Description

Technical Field

[0001] The utility model belongs to the technical field of template reinforcement, and particularly relates to a high-performance stainless steel back rib structure for reinforcing a column template. Background Art

[0002] Columns are common and main components in buildings. They are mainly vertical and used as supports. This type of column is mostly made of concrete, that is, concrete columns. Due to the different floor heights of buildings, the height of concrete columns will also vary. In the process of making concrete columns, concrete column formwork is needed to form a pouring space. The firmness of the concrete column formwork and the strength of the formwork are crucial to the formation of the concrete column.

[0003] The square column formwork is a formwork structure that surrounds the constructed steel frame with wooden boards or hard boards. By pouring concrete into the square column formwork, a square wooden pier support structure is formed after the concrete solidifies. The square column formwork is a formwork structure set up and used on the construction site. After the square column formwork is built, it needs to be fixed on the outside of the square column formwork. The prior art generally uses square tubes and tension bolts for locking. The fixing structure of the prior art generally locks the edge sides of the four sides of the square cone formwork, but it cannot be locked synchronously. When a single locking is performed, due to the excessive locking force, it is easy to cause the square column formwork to deflect on one side, making the final solidified square column part square. Even during the pouring process, due to uneven locking force, concrete leaks out, affecting the construction of the overall square column.

[0004] The patent publication number is: CN220705179U, and the patent name is: A steel back ribbed column formwork reinforcement device, which is designed to solve the reinforcement problem of the column formwork. However, due to its heavy weight, it is not easy to disassemble and assemble, resulting in low installation efficiency for workers. The system adopts a tic-tac-toe reinforcement method, and the length of the external tension screw required is relatively long. Utility Model Content

[0007] Furthermore, the bending angle of each stainless steel folding plate is 135°, and a plurality of threaded holes are respectively arranged on the upper and lower reinforcement surfaces. Two adjacent stainless steel folding plates are connected to the U-shaped square steel (5) as a whole by screws, and the other sides of the two adjacent stainless steel folding plates are arranged in contact with each other and fixed by screws.
